'0 all whom 'it may conce/rn` Be it known -that I, HERBERT J. BARNES, a citizen of the United States, residing et Reading, in the count)v of Berks and State 5 of Pennsylvanie, have invented certain new and useful Improvements-in Headlights, of which the following is e specicetion.

Y. My invention relates particularly to rond vehicle head lights having means for avoid- 10 ing the ordinary biinding eiect thereo, and

l y The upper portion of my improved headlight, as shown, isot1 ordinary forni. coniprising the usual parabolicl reflector 5, with A vertical circular window 6, and focal light 7; the projecting Wiringl 8 for the letter being inclosed as heretofore by en outer ce1sing 9. p

In my improved construction a supplemental reflector section i() is provided, extending jpartly around the parabolic rei'eetor 5; 'the leonveizlv,curved exterior 'well 15 of such inelosed portion of the letter being shoefii forniingvi-he upper reecting wall oi er section, and n conce y curved reiector Wei?. 16 forming the lovror 'irelector thereof. s' shown in Figs. Q end 3 the' sunplemental reector section i0 thus.' formed is of substantially crescent-shnped 40 crossjsection; the cross-sectione reducing in aren rearwardly to the intersect-ion 1'? of the reflector wallsl and 16. A separate iight 418, located forward of this intersection, is provided in the supplemental section 10; the

A connectedv'iring. being inclosed, :is shown,

by a continuation 9* of the inciosing casing 9 of the parabolic reector sectionueiid snitable swltches being provided for independently or .jointly controiiing the seperate lights. The *windowx S oi the snppiementei reiiec'stor` Section 10 .is.crescent shaped to correspond with the croefrectioiiei torni v qiieectiom end is inclined reeinveriy the plane of the circular Window 6, as shown, against the receding edge of the lower reflector 16. i

The supplemental refiector l@ is primarily intended to be thrown into service when the moin reector 5 if-throivn out tcgevoid Athe blinding1 eiect incident to the int-ter; though they may be used together When desired, either with the mein iight in reiector 5 or with a dimmer light as heretofore provided.

The forni and arrangement oi the supplemental refieetor l0 is adapted to reiiect its rays of iight into snhstnntiaiiy horizontal or downward lines.so as to inost setisie `torily illuminate the Whole road and the ad jacent side While avoiding any glare objectionable to an approaching driver. The described use Aoie. aA portion of the eXteriorsurfoce of the refiector 5 as the .top Wall of the supplemental reflector 10 is siinpe and wir rantageous, but :i separate wail plate Jfor such use may obviously be employed if de sired. and the shown construction othervviee modified 'Within the spirit of the invention.

1What Iclaim is:

l. In a headlight. a sup leniental substantiailwY semifparabolic re ector, a focal lamp arranged Within the exis or the reiiector. n mein .parabolic reiiector having a con sidereble portion belov/ its exis overhang ingr the of the lmnp in trie sup' nde ocfri innig; in the inc. the ailes of l fr' pe. te .eli ini having" .it Licei n in the exis thereof. a folic reflector hevinL' its outer surface provided to produce n reflecting surface for the lamp in the supple nient-el reflecting; section and a iocai iainp inthe moin parabolic reiiector, said inein parabolic reflector having a considerabie portion of its outer reecting surface overhanging the axis of the lampin the supplemental reiecting section.

3.
